What type of orbit would be used for a scientific satellite which needs to take regular readings to measure changes in the concentration of ozone gas in the stratosphere over Antarctica?
Satellites use specialized instruments called ozone mapping spectrometers to measure the amount of ozone in the stratosphere. These instruments collect data by detecting the amount of light absorbed by ozone molecules in the atmosphere.
Satellites typically use a polar orbit, which allows them to cross over the entire Antarctic region during each orbit. This provides more comprehensive coverage of the stratosphere and allows for more accurate measurements of ozone levels.
Scientists analyze the data collected by satellites over a period of time to track changes in ozone levels. By comparing data from different time periods, they can identify trends and patterns in ozone depletion or recovery.
Yes, satellites can measure ozone levels in the Antarctic stratosphere throughout the year. However, during the polar winter, when the sun does not rise above the horizon, the amount of light available for the satellites to collect data is limited.
Satellites can also collect data on other atmospheric components, such as temperature, humidity, and aerosols. This information can help scientists better understand the complex interactions within the stratosphere and how they contribute to ozone depletion.
